Patent GB-189908979-A (GB)
Title: Improvements in or relating to Roller Bearings and Ball Bearings.
Inventor: BRENNAN LOUIS
Filed: 1899-04-29
Granted: 1900-03-31
Abstract: 8979. Brennan, L. April 29. Casting.-Cages for rollers and ball bearings are cast around the rollers or balls themselves. It is necessary to use an alloy which melts at a temperature insufficient to injure the temper of the rollers or balls. A suitable alloy, which melts at about 300‹ F., consists of two parts of lead, two parts of tin, and one part of bismuth. Figs. 1 and 2 shows a cage b containing rollers a. The rollers a are placed between rings e, f having recesses e', f<1>, as shown in Fig. 4. The rings and rollers are then together placed in the mould c, d, Fig. 3, and the alloy is run in, filling the channels i and the spaces between the rollers. Fig. 8 shows a flat cage for the balls l of a thrust bearing. The cages may be strengthened by metal rings m<1>, or may be cast on to a metal framework. Such rings, or framework, may be tinned so that the metal cast on to them may be firmly united with them. In the case of a cage for conical rollers, a wheel-shaped frame of metal forms the foundation of the cage. A cage for a number of balls may be cast by the use of a rapidly-rotating mould. In carrying out this process, a mould cylinder t, Fig. 14, is secured in a chuck v, and, after balls e have been placed in it, is rotated at a high speed. While the balls are held against the cylinder t by centrifugal force, plaster of Paris is poured in in sufficient quantity to fill the space w. When the plaster has set, the rotation is stopped, and the cylinder t, with the balls embedded in the plaster, is taken out. The cylinder is then placed in a mould with a sufficient quantity of the alloy within it. The mould is next heated, in an oil bath or the like, and is then inserted in a chuck by which it is rotated. When the alloy has had time to set, the cage is taken out of the mould and the plaster removed. A cage of this kind, or a cage such as shown in Figs. 1 and 2, may be expanded by passing a mandrel through it, causing a slight enlargement of the ball or roller sockets. For large bearings, the cages may be made in sections, as indicated by the dotted lines 6 in Fig. 1.

Patent GB-190023597-A (GB)
Title: Improvements in or relating to Typewriting Machines.
Inventor: BOULT ALFRED JULIUS
Filed: 1900-12-24
Granted: 1901-11-02
Abstract: 23,597. Boult, A. J., [Sears, C.]. Dec. 24. Type-writers.-Relates to machines in which the type are carried upon more than one type-wheel or segment, shift-keys being employed to bring the various segments into use. Upon the upper or reduced end of a vertical stud B is mounted a sleeve C, free to turn but incapable of vertical movement. At its lower end the sleeve carries a flange c, which is operated by known means from the keyboard so as to turn the sleeve through various angular distances in two directions. The type - bearing segments D, D<1>, D<2> are loosely mounted on the sleeve C, but each is provided with a notch in its hub which can be engaged by a pin c<1> projecting rearwardly from the sleeve. The hubs of the type-segments are separated by the arms e' of a vertically-sliding bar E, which can be lifted by means of a lever J, rock-shaft j, and suitable shift-keys, so as to bring the intermediate or the lowest segment into the operative position, which is normally occupied by the top segment, as shown in Fig. 5. The pin c' keys the operative segment to the sleeve C, leaving the others loose thereon. The segments below the operative position are locked by the engagement of their stop arms d<3> in a notch a in the curved frame member A'. The segments, if any, above the operative position, are locked by the engagement of the curved head of a clamping-lever T in notches d<8> formed at the centres of the forwardly-extending flanges d<7>. One or more inking-rollers f, adapted to move over an inking-platen H, are carried by a pivoted arm suitably connected with the impression-hammer M. A blank space is left at the centre of each type-segment, so that the only type inked is that one on the operative segment which has been brought to the printing position. The inking-rollers may be of the same non-absorbent composition that is used for printing-press rollers. At the moment that the hammer M strikes the paper against the type, the operative segment is held firmly clamped by the following means :-An arm R fixed to the machine frame terminates in a rearwardly-projecting finger r, situated immediately beneath the flange d<7> of the operative segment. The notches d<8> enable the vertical shift of the segments to take place when they are all in the zero position, in spite of the presence of the finger r. As the hammer M approaches the impression point, the bar t is drawn down through the medium of a contractile spring t<3>, and the pivoted clamping-lever T closes firmly on the upper surface of the flange d<7>, which is thus gripped between the finger r and clamp T.
